Inventors and entrepreneurs who are looking to cut costs frequently want to do their own search. This is a wise first move, but you really need to be careful. It is quite common for inventors to search and find nothing even when there are things that could and would be found by a professional searcher. So while it makes sense to do your own search first, be careful relying on your own search to justify spending the thousands of dollars you will need to spend to ultimately obtain a patent. In other words, nothing in this article should be interpreted as me suggesting that inventors can or should forgo a professional patent search. There is simply no comparison between an inventor done patent search and a patent search done by a pro. Having said that, every inventor should spend time searching and looking if for no other reason than to familiarize themselves with the prior art. Of course, if you can find something that is too close on your own you save time and money and can move on to whatever invention/project is next. Another thing you MUST know about when you use Google Patent Search is that there are also some holes in the database. I have specifically looked for patents I know to exist and cannot always find them. I have heard the same experience from other patent attorneys and agents. Additionally, the most recent patents are not available on Google. What this means is you cannot only rely on Google, but you still must use Google. The Google database covers patents that are issued all the way back to US Patent No. 1. This scope is much broader than either Free Patents or the USPTO . So while you might not find everything, while it is difficult to specifically narrow your search, you still really need to check yourself using the Google database to see if there are old references that might be on point. In this case there are not many to choose from. Many times, however, the list will contain hundreds or even thousands of patents depending upon the popularity of the term or phrase selected. For example, if you search "SPEC/thermos", you will find hundreds of patents that use this word in the specification. In fact, at the time this sample search was conducted (March 16, 2012) no fewer than 970 US patents have the word "thermos" in the specification, and that is only for patents issued since 1976. So what should you do now? If you find too many patents, rework the specification field search. For example, if your search were "SPEC/thermos and SPEC/beverage" you get down to 200 US patents. Ultimately, upon receiving manageable results, just click on several of the patents. The key, however, is to start off broad and then narrow your way down to those that are the most likely relevant references. Also remember that it is critically important to figure out what things are called. I cannot stress this enough. You need to use different names and labels. You will find that patent attorneys typically call certain features by a select few names. These names are not always obvious, but once you figure out what the industry calls something you are far more likely to find relevant patents.How to Do a Patent Search For New Inventors and Students
Finding patents with a patent search is almost like being a detective. Have you ever gotten a cool toy or seen an interesting gadget and wondered how or who created it? When someone invents a new toy or gadget, they usually get a patent for it. A patent is a way that inventors can protect their ideas.Who owns a patent?
Patents are granted only in the name or names of the actual inventors. An inventor may sell, will, transfer or give all or any percentage of the rights to a patent to anyone. This is called patent assignment. Patents can also be licensed exclusively or non-exclusively.Is my idea already patented?
Most inventors dont really want to find their invention in someone elses patent, so the spend 5 minutes looking and then declare that they can't find it. It takes longer than that. If your invention is a mouse trap, you might find it by searching for those words...but the killer patent might instead describe a rodent restriction device or an automatic small animal containment system. Look for it like you want to find it. Talk to a registered patent attorney for immediate advice on protecting your idea (in the form of a provisional patent) while you determine if it is worth pursuing, in view of a preliminary search of related inventions, patented or not. Even if you don't find any "patents" showing your idea used in an invention, it could still be unpatentable because someone else used it or described it before you filed your provisional application.
